             Summary: Checking cache object type in runtime
                 Key: IGNITE-2909
                 URL: https://issues.apache.org/jira/browse/IGNITE-2909
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Denis Magda
            Priority: Critical
             Fix For: 1.6


In some cases there is necessity to control a type of object that is being
inserted into a cache.
Presently this kind of check is accomplished at compile time only relying
on Java Generics. However it doesn't prevent us from connecting to a
cluster using a non-generic instance of a cache and put any kind of data in
it. This may be not a harmful intention but rather a silly developer mistake.

The following solutions is proposed:
- if {{MutableConfiguration.setTypes(Class<K>
keyType, Class<V> valueType)}} are defined and not equal to Object.class then on every cache modification operation (put, invoke, etc.) type of a key and value has to be checked before being inserted;
- to support BinaryObjects we should introduce an additional method {{CacheConfiguration.setTypeNams(String keyType, String valueType)}} which will force checking of a key and value types the same way as above.
